more important is your choice of car
i've run a 70 comet moredoor, 72 fury II, 70 monte, 70 coupe deville and a 74 sedan deville before
the caddies have more frame than an f250 and 3 feet from the front bumper to the radiator
no fan, drilled hole in the radiator cap, radiused wheel openings, no stock wiring and a floor shifter will work magic
wire a start and run circuit direct to a battery mounted on the pass floor
a stock column shifter can be knocked loose, we used a maverick cable floor shifter, adjusted with no park and no locks. push forward to go forward, pull back for reverse
cut your exhaust off so you can hear it running over the noise or reverse the manifolds and run the tips thru the hood. it's quite impressive shooting flames at night.
rule number one: have fun
